    Help Identifying a blown Varistor

    I'm trying to identify this varistor to find a replacement, but I can't find any info on the manufacturer, and the markings don't match up with the standards I've seen. The first logo looks like an "SB", and the second an "H". the first numbers are either 13U2 or 1302, and the second numbers are 9810. I was expecting a format more like 130K, which would mean 13v +-10%. Anyone recognize the manufacturer's trademark or the specifications from the markings?

    That's a Harris 1302 Metal Oxide Varistor (MOV). Google 1302 MOV and you will find lots of information. The first mark is CSA, Canadian Standards Association, its a certification for the part because it is a critical safety component. The CSA mark is similar to the UL mark that is also on the part. The H in the middle is the Harris logo.

      And "9810" is the date code of the part. So it may just have been a gradual deterioration failure.

          Lightform LFC mini PC,Blown Component - Need help identifying or Next Steps
          by silver60618
          Hi gang, I have 2 of these Lightform LFC mini PC's, and both suffered a blown component near the 12V power input. Im assuming its a voltage regulator,
          But Im unable to identify the component or its marking. (The best I can make out is M48i)

          Can anyone help me clarify what this component maybe? or what would be the next troubleshooting or logical step to try next? Schematic is unavailable

          I removed the IC for better clarity of traces...

          How can I identify varistor which have been blew up?
          by chth96
          I mistakely pluged 100v japanese retro game console to 220v outlet.
          So It seems that glass fuse and varistor have been blew up.
          I can identify that voltage and ampere value of glass fuse(250V LF 1.6A),but It is impossible to identify varistor type in my sega saturn PSU(YAMAHA 35M07U XR258)
          Is there any way to identify varistor type in my sega saturn PSU?
          Any reply would be appreciated.


          EDIT:
          It seems that I finally found out what type this black varistor is. It is Panasonic ERZV05D221 “ZNR” Transient/Surge Absorbers (Type D) Varistor Voltage...

          Macintosh Quadra 840AV PSU
          by nicktasios
          I had my Quadra 840AV (which I recapped and had working) plugged in for some time without using it and randomly decided to turn it on today. Unfortunately it did not turn on. After checking the PSU, I found out I was not getting anything from 12V, only from the 5V rail. After a few minutes, I removed the PSU and plugged it back in the electrical outlet and it suddenly started making a weird sound and soon after smoke started coming out. I quickly unplugged it. I opened it up but on first instance I didn't see anything out of the ordinary really. I later turned it back on and one of the MOVs blew...

          LG 47LB5DF blown power supply board
          by cmlewis89
          Hi folks,

          I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown...
